Well, Kalli:

I at least THINK it's running rich. It smells REALLY bad out of the exhaust like a lot of unburned fuel. Also, I'm leaving a very faint cloud of smoke behind me when I accelerate. Also, when I come to a hard stop, the car dies.

I think that I can get the fuel/air mixture right but I don't think that the floats are correct. It says in a manual I bought for Holley Street Avengers that the fuel level in the little float windows should be at the bottom of the window. I can't seem to tune them correctly. The fuel line just won't seem to go lower than the top of the window.

Can somebody give me a good idea how to tune those properly?

THank you guys for the response.
